Tip led FBI to Exeter Sportsman's Club

EXETER - A tip from a local woman about a possible sighting of the Boston Marathon bombers a day before the attacks led the FBI to the Exeter Sportsman's Club earlier this week.

The woman reported an interaction she had with two men on April 14 who asked her for directions to the club.

Tom Wharton, vice president of the Exeter Sportsman's Club, said members of the FBI's Joint Terrorism Task Force contacted them Monday and spent about an hour with the club's security officer.

"They met with our security officer and went over all the tapes of the time in question ... and saw no suspicious people in the club and no car that matched her description," Wharton said. "We are proud we were able to help the FBI dispel this myth pretty quickly."

The club long ago placed itself under 24/7 surveillance and uses numerous infrared security cameras and an off-site recording system, which stores several weeks of video records.

Access to the range is also limited to members only through a locked gate.

"We require everybody to have had a background check before accepting them for membership. Then when they pay their dues and complete a safety inspection, they have access with a magnetic card," Wharton said.
